ESOPHAGEAL DELIVERY SYSTEM AND METHOD WITH POSITION INDEXING |
摘要 |
An esophageal delivery system includes features that facilitate the precise positioning of a medical device within the gastrointestinal tract. The system supports indexed positioning without relying solely on endoscopic viewing or external imaging equipment to identify the location of the medical devi`ce. A fixation element holds an elongated delivery device at a selected position within the gastrointestinal tract. The medical device is carried at a position that is a fixed and known distance away from the fixation element. Once the fixation element is positioned at a known location, precise positioning of the medical device within the esophagus can be achieved with greater certainty. As an illustration, the fixation element may take the form of a balloon an expandable frame or other device capable of engaging the lower esophageal sphincter (LES) to provide a reference position for a medical device to be placed at a precise distance above the LES. |
